Rubber-bridge theory

In the present poblem of telechelic polymers, the A-state corresponds to the bridge chain connecting the micellar junctions, while the B-state is the dangling chain. In affine network theory, va = ( X ) r as in (9.3), and vb = 0. But vb may also be affine if the B-state is another type of the elastically effective state, such as helical conformation or globular conformation of the same chain. We can study the stress relaxation in rubber networks in which chains change their conformation by deformation [30].
